"FEBA is an operational level, air-land battle simulation depicting modern mechanized war in Central Europe. Forces include the U.S. Army Seventh Corps and supporting West German brigades defending against invasion by Warsaw Pact forces through the Hof and Cheb Gaps. Both sides are massively supported by tactical airpower." FEBA was produced for the U.S. Air Force by Close Simulations as a part of Project Warrior. Avalon Hill would later print a revised version of the game under the name Tac Air.
